I also have an OCd E8400, which until last week was at 4.01GHz (on a fanless heatsink). Out of curiosity, what voltage are you running it at? Same for RAM and FSB.
I downclocked mine back down to 3.6GHz @ 1.2375V. FSB is 1.3V, and RAM is 1.875V
I really wish I'd written down my 4GHz voltages etc. :-|
Thanks, like I said it's been way too long, I miss getting my geek on, haha. I'm probably just going to grab some DDR2 1066 with known overclocking capability and strong latency speeds and call it a day.
To be honest I haven't been rambling around in my BIOS for too long so I can't be sure, I do know that when I was trying to find a stable table of values I spent days playing with everything before I got it right.
At a glance CPU-Z is telling me 1.312v core voltage (under < %5 load) , so I believe I have it set somewhere near 1.3375v in BIOS, my FSB volatge is probably whatever the motherboard chose for it because i remember it being fussy when I messed with it. My RAM is @ 2.0125v over clocked to 900mhz.
With that said those voltages are for stability so I rounded them up. I've been running this for at least a year in this state with no blue screens to thinkg of besides those which I caused trying to squeeze my gfx cards..
Hope that helps...
Looking at that picture it obvious and I feel so newbish at this point. I can't wait to get some more capable RAM. Does anyone have suggestions? I know this forum is absolutely notorious for people spitting out good suggestions (at least last time I was online) so I figured someone will know what I need and be on point.
